1、 The newly installed dispatch winch must be designed by mining professionals, and the installation and recycling principles of the underground mining winch are the responsibility of the mechanical and electrical section.
In the installation design, it is necessary to clearly mark the dimensions of the mine winch chamber, winch model, control equipment model, winch installation location, installation dimensions, lighting and signal installation positions, steel wire rope model, length, load capacity, rope head connection method, and downhill safety facilities (installation dimensions and specific requirements of car stops, safety doors, and ground rollers, etc.)
2、 Temporarily used and with a traction angle of no more than 15 ° for inclined tunnels
3、 When the load is less than three-quarters of the rated load of the underground mining winch, two pressure pillars can be used for fixation. The fixation of the pressure pillars must be checked frequently.
The installation quality of all dispatch winch should meet the requirements of design and installation quality standards. After installation is completed, they should be accepted and qualified before being put into use.
4、 When the traction slope length of the dispatching winch exceeds 15m, sound and light signals must be installed. The signal line should use rubber sheathed cables, and there should be no chicken paws, sheep tails, or exposed joints. The power switch of the dispatch winch must be operated by a remote control button.
5、 Dispatch winch management requires a dedicated person to charter the machine, and whoever uses it will manage it, keeping it in good condition, ensuring the safety of the winch clutch, braking system, rope guard, etc
The device must be complete and reliable. Otherwise, it is not allowed to use. The steel wire rope, hook head, and connecting device of the lifting vehicle must meet the requirements. The trailer must use a safety hook head, and when the inclination angle is greater than 12 °, a safety rope must be used.
6、 The underground mining winch must implement the principle of shift inspection during use, and the shift inspection is the responsibility of the driver.
7、 Regular maintenance should be carried out on the dispatch winch, and it is prohibited to switch or use it beyond the specified period underground. The dispatch mine winch after the upwell overhaul should have a dedicated person responsible for quality inspection, and unqualified ones are not allowed to be used.
8、 The driver of the dispatch winch must be assigned a dedicated person who has received technical training and passed the assessment before taking up the job with a certificate. Driving without a certificate is not allowed
The mine winch must strictly adhere to the job responsibility system and the "Operating Regulations", and overloading and transportation are strictly prohibited. It is strictly prohibited to not send or discharge electric vehicles.
9、 The steel wire ropes and safety ropes used for hoisting the dispatch winch must strictly follow the daily inspection system, which is the responsibility of the driver of the using unit. In special cases (abnormal changes occur, and the driver is not able to grasp them on time), they should be reported to the dispatching room, and a dedicated mechanical and electrical rope inspector should be designated to sign on site. A steel wire rope inspection record book is established at the site of winch use, and detailed records of rope inspection are kept on it every day.
10、 All locations where mine winch are used must have a complete "Operating Regulations" and a job responsibility system, as well as a winch technical feature board.
